Variable-speed phonetic pronunciation machine

ABSTRACT

A machine causes a touch-sensitive screen to present a graphical user interface that depicts a slider control aligned with a word that includes a first alphabetic letter and a second alphabetic letter. A first zone of the slider control corresponds to the first alphabetic letter, and a second zone of the slider control corresponds to the second alphabetic letter. The machine detects a touch-and-drag input that begins within the first zone and enters the second zone. In response to the touch-and-drag input beginning within the first zone, the machine presents a first phoneme that corresponds to the first alphabetic letter, and the presenting of the first phoneme may include audio playback of the first phoneme. In response to the touch-and-drag input entering the second zone, the machine presents a second phoneme that corresponds to the second alphabetic letter, which may include audio playback of the second phoneme.

TECHNICAL FIELD

The subject matter disclosed herein generally relates to the technicalfield of special-purpose machines that facilitate teaching or learningof reading skills, including software-configured computerized variantsof such special-purpose machines and improvements to such variants, andto the technologies by which such special-purpose machines becomeimproved compared to other special-purpose machines that facilitateteaching or learning of reading skills. Specifically, the presentdisclosure addresses systems and methods to facilitate variable-speedphonetic pronunciation of alphabetic letters (e.g., variable-speedpronunciation of a word made of multiple alphabetic letters) and wordscomposed thereof.

BACKGROUND

A machine may be configured to interact with one or more users of themachine (e.g., a computer or other device) by presenting an exercisethat teaches one of more reading skills to the one or more users orotherwise guides the one or more users through practice of the one ormore reading skills. For example, the machine may present an alphabeticletter (e.g., the letter “A” or the letter “B”) within a graphical userinterface (GUI), play an audio or video recording of an actorpronouncing the presented alphabetic letter, and then prompt a user(e.g., a child who is learning to read) to also pronounce the presentedalphabetic letter.

DETAILED DESCRIPTION

Example methods (e.g., algorithms) facilitate variable-speedpronunciation of phonemes by a machine, and example systems (e.g.,special-purpose machines configured by special-purpose software) areconfigured to facilitate (e.g., perform) variable-speed pronunciation ofphonemes. Examples merely typify possible variations. Unless explicitlystated otherwise, structures (e.g., structural components, such asmodules) are optional and may be combined or subdivided, and operations(e.g., in a procedure, algorithm, or other function) may vary insequence or be combined or subdivided. In the following description, forpurposes of explanation, numerous specific details are set forth toprovide a thorough understanding of various example embodiments. It willbe evident to one skilled in the art, however, that the present subjectmay be practiced without these specific details.

A machine may be specially configured (e.g., by suitable hardwaremodules, software modules, or a combination of both) to behave orotherwise function as a variable-speed phonetic pronunciation machinethat, for example, pronounces the phonemes of a word at a pronunciationspeed that varies in accordance with a variable-speed user input, suchas a touch-and-drag input on a touch-sensitive display screen. Inaccordance with the systems and methods discussed herein, thevariable-speed phonetic pronunciation machine is technically improvedcompared to other machines that also pronounce phonemes but lack thebehaviors described herein. Such technical improvements include beingmore responsive to a user (e.g., as the user dynamically varies thespeed of the touch-and-drag input), providing a greater degree ofcontrol (e.g., over the speed at which the word is pronounced) to theuser, providing more natural sounding auditory feedback to the user(e.g., at high pronunciation speeds, at low pronunciation speeds, orboth), providing more natural looking visual feedback (e.g., in the formof animated mouth movements presented on a display screen) to the user,enabling the user to quickly and conveniently experiment with severaldifferent pronunciation speeds for a word (e.g., by repeatedlypronouncing the word in response to repeated touch-and-drag inputs atdifferent speeds), or any suitable combination thereof.

To provide these technical features and benefits, the variable-speedphonetic pronunciation machine is configured to present a GUI on atouch-sensitive display screen of the machine, where the GUI depicts aslider control that is aligned with a word. The word includes (e.g., atleast) a sequentially first alphabetic letter and a sequentially secondalphabetic letter. As depicted in the GUI, a first zone of the slidercontrol corresponds to the sequentially first alphabetic letter of theword, and a second zone of the slider control corresponds to thesequentially second alphabetic letter of the word.

The machine is further configured to detect, via the touch-sensitivedisplay screen, a touch-and-drag input (e.g., a swipe gesture) thatbegins within the first zone of the slider control and enters the secondzone of the slider control. In response to the touch-and-drag inputbeginning within the first zone of the slider control, the machinepresents or otherwise causes presentation of a first phoneme thatcorresponds to the sequentially first alphabetic letter of the word, andthe presenting of the first phoneme may include audio playback of thefirst phoneme. In response to the touch-and-drag input entering thesecond zone of the slider control, the machine presents or otherwisecauses presentation of a second phoneme that corresponds to thesequentially second alphabetic letter of the word, and the presenting ofthe second phoneme may include audio playback of the second phoneme.

FIGS. 1-5 are face views of a machine 100 (e.g., a device, such as amobile device) with a display screen 101 on which a GUI 110 suitable forvariable-speed phonetic pronunciation is presented, according to someexample embodiments. As shown in FIG. 1, the display screen 101 istouch-sensitive and configured to accept one or more touch inputs fromone or more fingers of a user, and as an example, a finger 140 isillustrated as touching the display screen 101 of the machine 100.

The GUI 110 is presented on the display screen 101 and depicts (e.g.,among other things) a word 120 (e.g., “CAT,” as depicted, oralternatively “DOG,” “MOM,” “DAD,” “BABY,” “APPLE,” “SCHOOL,” or“BACKPACK”) and a slider control 130 (e.g., a slider bar). The slidercontrol 130 may be visually aligned with the word 120. For example, boththe slider control 130 and the word 120 may follow the same straightline or follow two parallel lines. As another example, both the slidercontrol 130 and the word 120 may follow the same curved line or followtwo curved lines that are a constant distance apart.

As shown in FIG. 1, the slider control 130 may include a slide element131, such as a position indicator bar or other marker (e.g., a cursor)that indicates progress in pronouncing the word 120 or its phonemes. Asfurther shown in FIG. 1, the word 120 includes one or more alphabeticletters and may therefore include (e.g., among other text characters) asequentially first alphabetic letter 121 (e.g., “C”) and a sequentiallysecond alphabetic letter 122 (e.g., “A”). The word 120 may furtherinclude a third alphabetic letter 123 (e.g., “T”). For example, the word120 may be a consonant-vowel-consonant (CVC) word, such as “cat” or“dog,” and accordingly include the sequentially first alphabetic letter121, the sequentially second alphabetic letter 122, and the sequentiallythird alphabetic letter 123.

Different zones of the slider control 130 correspond to differentalphabetic letters of the word 120, and each zone of the slider control130 may be visually aligned with its corresponding alphabetic letter ofthe word 120. Hence, with reference to FIG. 1, a first zone of theslider control 130 corresponds to the sequentially first alphabeticletter 121 (e.g., “C”) and may be visually aligned with the sequentiallyfirst alphabetic letter 121, and a second zone of the slider control 130corresponds to the sequentially second alphabetic letter 122 (e.g., “A”)and may be visually aligned with the sequentially second alphabeticletter 122. Similarly, a third zone of the slider control 130 maycorrespond to the sequentially third alphabetic letter 123 (e.g., “T”)and may be visually aligned with the sequentially third alphabeticletter 123.

In addition, the GUI 110 may include an avatar 150 or other character(e.g., a cartoon character), and the avatar 150 may be animated orotherwise rendered (e.g., in two dimensions or in three dimensions) withone or more moving parts. For example, the avatar 150 may have ananimated mouth 151 that changes its shape based on (e.g., in accordancewith, in response to, or both) the phoneme currently being pronounced bythe machine 100.

As shown in FIG. 1, the finger 140 is performing a touch-and-drag input(e.g., a swipe gesture) on the display screen 101. To start thetouch-and-drag input, the finger 140 is touching the display screen 101at a location (e.g., a first location) that is within the first zone ofthe slider control 130, and the display screen 101 detects that thefinger 140 is touching the display screen 101 at that location.Accordingly, the touch-and-drag input is beginning (e.g., touching down)within the first zone of the slider control 130. As noted above, thefirst zone of the slider control 130 corresponds to the sequentiallyfirst alphabetic letter 121 (e.g., “C”). In response to detection of thefinger 140 touching the illustrated location within the GUI 110, the GUI110 presents the slide element 131 at the same location. As noted above,the slide element 131 may indicate an extent of progress attained inpronouncing the phonemes of the word 120 (e.g., no progress, asillustrated in FIG. 1). The animated mouth 151 of the avatar 150 mayaccordingly be shown in a neutral shape (e.g., a neutral mouth shape,such as a smile or an expressionless shape with closed lips).

In response to the touch-and-drag input beginning within the first zoneof the slider control 130, the machine 100 presents a first phoneme thatcorresponds to the sequentially first alphabetic letter 121 (e.g., “C”)that corresponds to the first zone of the slider control 130. Thispresenting of the first phoneme may include audio playback of the firstphoneme (e.g., audio playback of a sound file that records an actorpronouncing the first phoneme). According to some example embodiments,the presenting of the first phoneme includes displaying the animatedmouth 151 in a first shape (e.g., a first mouth shape) that correspondsto the first phoneme, and the displaying up to the animated mouth 151 inthe first shape may be maintained during the audio playback of the firstphoneme. In certain example embodiments, the presenting of the firstphoneme includes or is accompanied by changing the color of thesequentially first alphabetic letter 121 (e.g., from a first color to asecond color during the audio playback of the first phoneme and thenchanging its color back again after the audio playback of the firstphoneme).

As shown in FIG. 2, the finger 140 continues to perform thetouch-and-drag input on the display screen 101, and the touch-and-draginput is still within the first zone of the slider control 130. That is,the finger 140 is touching the display screen 101 at a location (e.g., asecond location) that is within the first zone of the slider control130, and the display screen 101 detects that the finger 140 is touchingthe display screen 101 at that location. Accordingly, the touch-and-draginput continues but remains within the first zone of the slider control130. In response to detection of the finger 140 touching the illustratedlocation within the GUI 110, the GUI 110 presents the slide element 131at the same location. As noted above, the slide element 131 may indicatean extent of progress attained in pronouncing the phonemes of the word120 (e.g., progress up to pronunciation of the phoneme that correspondsto the first sequential alphabetic letter, as illustrated in FIG. 2).

In response to the touch-and-drag input remaining within the first zoneof the slider control 130, in situations where the first phoneme is avowel phoneme, the machine 100 may sustain (e.g., prolong) the audioplayback of the first phoneme. This may be performed by repeatedlylooping at least a portion of the vowel phoneme, and such repeatedlooping may be performed for as long as the touch-and-drag input remainswithin the first zone of the slider control 130. On the other hand, inresponse to the touch-and-drag input remaining within the first zone ofthe slider control 130, in situations where the first phoneme is aconsonant phoneme, the machine 100 may stop (e.g., cease) the audioplayback of the consonant phoneme after exactly one iteration. Forexample, the machine 100 may start to playback silence after completionof a single playback of the consonant phoneme and thereafter continue toplayback silence as long as the touch-and-drag input remains within thefirst zone of the slider control 130. As another example, the machine100 may limit itself to playing back only background sounds, backgroundmusic, or any suitable combination thereof, without playing back anyforeground audio, such as recorded or synthesized speech, as long as thetouch-and-drag input remains within the first zone of the slider control130.

As shown in FIG. 3, the finger 140 continues to perform thetouch-and-drag input on the display screen 101, and the touch-and-draginput has entered the second zone of the slider control 130. That is,the finger 140 is touching the display screen 101 at a location (e.g., athird location) that is within the second zone of the slider control130, and the display screen 101 detects that the finger 140 is touchingthe display screen 101 at that location. Accordingly, the touch-and-draginput continues and is now within the second zone of the slider control130. In response to detection of the finger 140 touching the illustratedlocation within the GUI 110, the GUI 110 presents the slide element 131at the same location. As noted above, the slide element 131 may indicatean extent of progress attained in pronouncing the phonemes of the word120 (e.g., progress up to pronunciation of the phoneme that correspondsto the second sequential alphabetic letter, as illustrated in FIG. 3).

In response to the touch-and-drag input entering the second zone of theslider control 130, the machine 100 presents a second phoneme thatcorresponds to the sequentially second alphabetic letter 122. (e.g.,“A”) that corresponds to the second zone of the slider control 130. Thispresenting of the second phoneme may include audio playback of thesecond phoneme (e.g., audio playback of a sound file that records anactor pronouncing the second phoneme). According to some exampleembodiments, the presenting of the second phoneme includes displayingthe animated mouth 151 in a second shape (e.g., a second mouth shape)that corresponds to the second phoneme, and the displaying of theanimated mouth 151 in the second shape may be maintained during theaudio playback of the second phoneme. In certain example embodiments,the presenting of the second phoneme includes or is accompanied bychanging the color of the sequentially second alphabetic letter 122(e.g., from a first color to a second color during the audio playback ofthe second phoneme, and then changing its color back again after theaudio playback of the second phoneme).

Furthermore, in response to the touch-and-drag input remaining withinthe second zone of the slider control 130, in situations where thesecond phoneme is a vowel phoneme, the machine 100 may sustain (e.g.,prolong) the audio playback of the second phoneme. This may be performedby repeatedly looping at least a portion of the vowel phoneme, and suchrepeated looping may be performed for as long as the touch-and-draginput remains within the second zone of the slider control 130. On theother hand, in response to the touch-and-drag input remaining within thesecond zone of the slider control 130, in situations where the secondphoneme is a consonant phoneme, the machine 100 may stop (e.g., cease)the audio playback of the consonant phoneme after exactly one iteration.For example, the machine 100 may start to playback silence aftercompletion of a single playback of the consonant phoneme and thereaftercontinue to playback silence as long as the touch-and-drag input remainswithin the second zone of the slider control 130. As another example,the machine 100 may limit itself to playing back only background sounds,background music, or any suitable combination thereof, without playingback any foreground audio, such as recorded or synthesized speech, aslong as the touch-and-drag input remains within the second zone of theslider control 130.

As shown in FIG. 4, the finger 140 continues to perform thetouch-and-drag input on the display screen 101, and the touch-and-draginput has entered the third zone of the slider control 130. That is, thefinger 140 is touching the display screen 101 at a location (e.g., afourth location) that is within the third zone of the slider control130, and the display screen 101 detects that the finger 140 is touchingthe display screen 101 at that location. Accordingly, the touch-and-draginput continues and is now within the third zone of the slider control130. In response to detection of the finger 140 touching the illustratedlocation within the GUI 110, the GUI 110 presents the slide element 131at the same location. As noted above, the slide element 131 may indicatean extent of progress attained in pronouncing the phonemes of the word120 (e.g., progress up to pronunciation of the phoneme that correspondsto the third sequential alphabetic letter, as illustrated in FIG. 4).

In response to the touch-and-drag input entering the third zone of theslider control 130, the machine 100 presents a third phoneme thatcorresponds to the sequentially third alphabetic letter 123 (e.g., “T”)that corresponds to the third zone of the slider control 130. Thispresenting of the third phoneme may include audio playback of the thirdphoneme (e.g., audio playback of a sound file that records an actorpronouncing the third phoneme). According to some example embodiments,the presenting of the third phoneme includes displaying the animatedmouth 151 in a third shape (e.g., a second third shape) that correspondsto the third phoneme, and the displaying up to the animated mouth 151 inthe third shape may be maintained during the audio playback of thesecond phoneme. In certain example embodiments, the presenting of thethird phoneme includes or is accompanied by changing the color of thesequentially third alphabetic letter 123 (e.g., from a first color to asecond color during the audio playback of the third phoneme, and thenchanging its color back again after the audio playback of the thirdphoneme).

Furthermore, in response to the touch-and-drag input remaining withinthe third zone of the slider control 130, in situations where the thirdphoneme is a vowel phoneme, the machine 100 may sustain (e.g., prolong)the audio playback of the third phoneme. This may be performed byrepeatedly looping at least a portion of the vowel phoneme, and suchrepeated looping may be performed for as long as the touch-and-draginput remains within the third zone of the slider control 130. On theother hand, in response to the touch-and-drag input remaining within thethird zone of the slider control 130, in situations where the thirdphoneme is a consonant phoneme, the machine 100 may stop (e.g., cease)the audio playback of the consonant phoneme after exactly one iteration.For example, the machine 100 may start to playback silence aftercompletion of a single playback of the consonant phoneme and thereaftercontinue to playback silence as long as the touch-and-drag input remainswithin the third zone of the slider control 130. As another example, themachine 100 may limit itself to playing back only background sounds,background music, or any suitable combination thereof, without playingback any foreground audio, such as recorded or synthesized speech, aslong as the touch-and-drag input remains within the third zone of theslider control 130.

As shown in FIG. 5, the finger 140 is finishing the touch-and-drag inputon the display screen 101 by just lifting off the display screen 101 ata location (e.g., a fifth location) that is within the third zone of theslider control 130, and the display screen 101 detects that the finger140 has moved to this location on the display screen 101 and thenstopped contacting the display screen 101. Accordingly, thetouch-and-drag input has ended within the third zone of the slidercontrol 130. As noted above, the third zone of the slider control 130corresponds to the sequentially third alphabetic letter 123 (e.g., “T”).In response to detection of the finger 140 lifted off the display screen101 at the illustrated location within the GUI 110, the GUI 110 presentsthe slide element 131 at the same location. As noted above, the slideelement 131 may indicate an extent of progress attained in pronouncingthe phonemes of the word 120 (e.g., progress to completion, asillustrated in FIG. 5). The animated mouth 151 of the avatar 150 mayaccordingly revert to a neutral shape (e.g., a neutral mouth shape, suchas a smile or an expressionless shape with closed lips).

FIG. 6 is a block diagram illustrating components of the machine 100, asconfigured for variable-speed phonetic pronunciation, according to someexample embodiments. The machine 100 is shown as including a touch inputdetector 610, a phoneme presentation generator 620, and the displayscreen 101, all configured to communicate with each other (e.g., via abus, shared memory, or a switch). The touch input detector 610 may be orinclude a touch input module or similarly suitable software code fordetecting one or more touch inputs (e.g., a touch-and-drag input)occurring on the display screen 101. The phoneme presentation generator620 may be or include a phoneme rendering module or similarly suitablesoftware code for rendering or otherwise generating a presentation ofone or more phonemes (e.g., via the machine 100 or any portion thereof,including via the GUI 110, via an audio playback subsystem of themachine 110, or both).

As shown in FIG. 6, the touch input detector 610, the phonemepresentation generator 620, or both, may form all or part of an app 600(e.g., a mobile app) that is stored (e.g., installed) on the machine 100(e.g., responsive to or otherwise as a result of data being receivedfrom one or more server machines via a network). Furthermore, one ormore processors 699 (e.g., hardware processors, digital processors, orany suitable combination thereof) may be included (e.g., temporarily orpermanently) in the app 600, the touch input detector 610, the phonemepresentation generator 620, or any suitable combination thereof.

Any one or more of the components (e.g., modules) described herein maybe implemented using hardware alone (e.g., one or more of the processors699) or a combination of hardware and software. For example, anycomponent described herein may physically include an arrangement of oneor more of the processors 699 (e.g., a subset of or among the processors699) configured to perform the operations described herein for thatcomponent. As another example, any component described herein mayinclude software, hardware, or both, that configure an arrangement ofone or more of the processors 699 to perform the operations describedherein for that component. Accordingly, different components describedherein may include and configure different arrangements of theprocessors 699 at different points in time or a single arrangement ofthe processors 699 at different points in time. Each component (e.g.,module) described herein is an example of a means for performing theoperations described herein for that component. Moreover, any two ormore components described herein may be combined into a singlecomponent, and the functions described herein for a single component maybe subdivided among multiple components. Furthermore, according tovarious example embodiments, components described herein as beingimplemented within a single system or machine (e.g., a single device)may be distributed across multiple systems or machines (e.g., multipledevices).

The machine 110 may be, include, or otherwise be implemented in aspecial-purpose (e.g., specialized or otherwise non-conventional andnon-generic) computer that has been modified to perform one or more ofthe functions described herein (e.g., configured or programmed byspecial-purpose software, such as one or more software modules of aspecial-purpose application, operating system, firmware, middleware, orother software program). For example, a special-purpose computer systemable to implement any one or more of the methodologies described hereinis discussed below with respect to FIG. 11, and such a special-purposecomputer may accordingly be a means for performing any one or more ofthe methodologies discussed herein. Within the technical field of suchspecial-purpose computers, a special-purpose computer that has beenspecially modified (e.g., configured by special-purpose software) by thestructures discussed herein to perform the functions discussed herein istechnically improved compared to other special-purpose computers thatlack the structures discussed herein or are otherwise unable to performthe functions discussed herein. Accordingly, a special-purpose machineconfigured according to the systems and methods discussed hereinprovides an improvement to the technology of similar special-purposemachines.

Accordingly, the machine 100 may be implemented in the special-purpose(e.g., specialized) computer system, in whole or in part, as describedbelow with respect to FIG. 11. According to various example embodiments,the machine 100 may be or include a desktop computer, a vehiclecomputer, a home media system (e.g., a home theater system or other homeentertainment system), a tablet computer, a navigational device, aportable media device, a smart phone, or a wearable device (e.g., asmart watch, smart glasses, smart clothing, or smart jewelry).

FIGS. 7-10 are flowcharts illustrating operations of the machine 100 inperforming a method 700 of variable-speed phonetic pronunciation,according to some example embodiments. Operations in the method 700 maybe performed by the machine 100, using components (e.g., modules)described above with respect to FIG. 6, using one or more processors(e.g., microprocessors or other hardware processors), or using anysuitable combination thereof. As shown in FIG. 7, the method 700includes operations 710, 720, 730, and 740.

In operation 710, the app 600 presents the GUI 110 on the display screen101 (e.g., a touchscreen or other touch-sensitive display screen) orotherwise causes the GUI 110 to be presented on the display screen 101.As noted above, the GUI 110 depicts the slider control 130, and theslider control 130 is aligned with the word 120, which is also depictedby the GUI 110. As further noted above, the word 120 includes (e.g., atleast) the sequentially first alphabetic letter 121 and the sequentiallysecond alphabetic letter 122. Furthermore, a first zone of the slidercontrol 130 (e.g., a region of the slider control 130 near thesequentially first alphabetic letter 121) corresponds to thesequentially first alphabetic letter 121, and a second zone of theslider control (e.g., a region of the slider control 130 near thesequentially second alphabetic letter 122) corresponds to thesequentially second alphabetic letter 122. In some example embodiments,operation 710 is performed by the phoneme presentation generator 620 ofthe app 600. The visual effect of operation 710 may appear asillustrated in FIG. 1.

In operation 720, the touch input detector 610 detects (e.g., via,using, in conjunction with, or otherwise based on the display screen101) a touch-and-drag input that begins within the first zone of theslider control 130 and enters the second zone of the slider control 130.The visual effect of operation 720 may appear as illustrated in FIGS.1-3.

In operation 730, the phoneme presentation generator 620 responds to thetouch-and-drag input beginning within the first zone of the slidercontrol 130 by presenting a first phoneme that corresponds to thesequentially first alphabetic letter 121 of the word 120. As noted abovewith respect to FIG. 1 and FIG. 2, the presenting of the first phonememay include performing or otherwise causing audio playback of the firstphoneme (e.g., among other things).

In operation 740, the phoneme presentation generator 620 responds to thetouch-and-drag input entering the second zone of the slider control 130by presenting a second phoneme that corresponds to the sequentiallysecond alphabetic letter 122 of the word 120. As noted above withrespect to FIG. 3, the presenting of the second phoneme may includeperforming or otherwise causing audio playback of the second phoneme(e.g., among other things).

As shown in FIG. 8, in addition to any one or more of the operationspreviously described, the method 700 may include one or more ofoperations 820, 830, 832, 840, and 842. Operation 820 may be performedas part (e.g., a precursor task, a subroutine, or a portion) ofoperation 720, in which the touch input detector 610 detects that thetouch-and-drag input starts in the first zone of the slider control 130and enters the second zone of the slider control 130. In operation 820,that touch input detector 610 triggers a presenting of a pronunciationof the word 120 in response to the detecting of the touch-and-draginput.

For example, in example embodiments that include operation 820, thetouch-and-drag input may have a certain duration, and the touch inputdetector 610 may trigger presentation of a pronunciation whose durationis coextensive with the duration of the touch-and-drag input (e.g.,however long that duration turns out to be). In this situation, thepresenting of the pronunciation of the word 120 may include performingdownstream operations 730 and 740, in which the first and secondphonemes are presented, within the duration of the touch-and-drag input.

As another example, in example embodiments that include operation 820,the touch-and-drag input may have a certain speed (e.g., a movementspeed on the display screen 101), and the touch input detector 610 maytrigger presentation of a pronunciation at a speed (e.g., a speech speedat which successive phonemes of the word 120 are played back) that isdetermined based on the speed (e.g., movement speed) of thetouch-and-drag input. In this situation, the presenting of thepronunciation of the word 128 may include performing downstreamoperations 730 and 740, in which the first and second phonemes arepresented, at the speech speed determined based on the movement speed ofthe touch-and-drag input.

As part of operation 730, either operation 830 or operation 832 may beperformed, depending on whether the first phoneme that corresponds tothe sequentially first alphabetic letter 121 is a consonant phoneme or avowel phoneme. In operation 830, the first phoneme is a vowel phoneme,and the phoneme presentation generator 620, as part of presenting thefirst phoneme, sustains (e.g., prolongs) the vowel phoneme for anindefinite duration as long as the touch-and-drag input stays in thefirst zone of the slider control 130 (e.g., until the touch-and-draginput exits the first zone). As noted above, this may be performed bylooping at least a portion of the vowel phoneme as long as thetouch-and-drag input remains in the first zone. Alternatively, inoperation 832, the first phoneme is a consonant phoneme, and the phonemepresentation generator 620, as part of presenting the first phoneme,plays the consonant phoneme followed by silence for an indefiniteduration as long as the touch-and-drag input stays in the first zone ofthe slider control 130 (e.g., until the touch-and-drag input exits thefirst zone). As noted above, this may be performed by playing back theconsonant phoneme exactly once and then playing back silence or playingback only background audio (e.g., background sounds, background music,or both) without any foreground audio (e.g., without any recordedspeech, synthesized speech, or both).

As part of operation 740, either operation 840 or operation 842 may beperformed, depending on whether the second phoneme that corresponds tothe sequentially second alphabetic letter 122 is a consonant phoneme ora vowel phoneme. In operation 840, the second phoneme is a vowelphoneme, and the phoneme presentation generator 620, as part ofpresenting the second phoneme, sustains (e.g., prolongs) the vowelphoneme for an indefinite duration as long as the touch-and-drag inputstays in the second zone of the slider control 130 (e.g., until thetouch-and-drag input exits the second zone). As noted above, this may beperformed by looping at least a portion of the vowel phoneme as long asthe touch-and-drag input remains in the second zone. Alternatively, inoperation 842, the second phoneme is a consonant phoneme, and thephoneme presentation generator 620, as part of presenting the secondphoneme, plays the consonant phoneme followed by silence for anindefinite duration as long as the touch-and-drag input stays in thesecond zone of the slider control 130 (e.g., until the touch-and-draginput exits the second zone). As noted above, this may be performed byplaying back the consonant phoneme exactly once and then playing backsilence or playing back only background audio (e.g., background sounds,background music, or both) without any foreground audio (e.g., withoutany recorded speech, synthesized speech, or both).

As shown in FIG. 9, in addition to any one or more of the operationspreviously described, the method 700 may include one or more ofoperations 930, 932, 940, and 942.

One or both of operation 930 and operation 932 may be performed as partof operation 730, according to various example embodiments. In operation930, the phoneme presentation generator 620, as part of presenting thefirst phoneme, depicts or causes the GUI 110 to depict the animatedmouth 151 of the avatar 150 in a first shape (e.g., a first mouth shape)that corresponds to the first phoneme. This may be performed byaccessing and rendering a two-dimensional image of the first shape or athree-dimensional model of the first shape or otherwise causing such atwo-dimensional image or a three-dimensional model to be accessed andrendered by the GUI 110.

In operation 932, the phoneme presentation generator 620, as part ofpresenting the first phoneme, changes the color of the sequentiallyfirst alphabetic letter 121 by changing the color from a first color(e.g., a default color, such as blue) to a second color (e.g., ahighlight color, such as yellow).

One or both of operation 940 and operation 942 may be performed as partof operation 740, according to various example embodiments. In operation940, the phoneme presentation generator 620, as part of presenting thesecond phoneme, depicts or causes the GUI 110 to depict the animatedmouth 151 of the avatar 150 in a second shape (e.g., a second mouthshape) that corresponds to the second phoneme. This may be performed byaccessing and rendering a two-dimensional image of the second shape or athree-dimensional model of the second shape or otherwise causing such atwo-dimensional image or a three-dimensional model to be accessed andrendered by the GUI 110.

In operation 942, the phoneme presentation generator 620, as part ofpresenting the second phoneme, changes the color of the sequentiallysecond alphabetic letter 122 by changing the color from a first color(e.g., a default color, such as blue) to a second color (e.g., ahighlight color, such as yellow).

As shown in FIG. 10, in addition to any one or more of the operationspreviously described, the method 700 may include one or more ofoperations 1050, 1052, 1060, 1062, 1080, and 1082.

According to certain example embodiments, individual touch inputs onindividual alphabetic letters 121, 122, and 123 of the word 120 aredetected by the touch input detector 610 (e.g., via the display screen101), and each individual touch input on an individual alphabetic letter(e.g., on the first sequential alphabetic letter 121) triggerspresentation of the corresponding phoneme for that alphabetic letter(e.g., audio playback of the first phoneme, with or without the animatedmouth 151 changing shape to a corresponding mouth shape, and with orwithout changing the color of the first sequential alphabetic letter121).

In operation 1050, the touch input detector 610 detects (e.g., via,using, in conjunction with, or otherwise based on the display screen101) a touch input (e.g., a single tap or a double tap) at a location ofthe display screen 101 where the GUI 110 is presenting (e.g.,displaying) the sequentially first alphabetic letter 121 (e.g., “C”)within the word 120. In response, in operation 1052, the phonemepresentation generator 620 presents the first phoneme that correspondsto the sequentially first alphabetic letter 121 of the word 120. Such apresentation may be performed in a manner similar to that describedabove for the first phoneme. For example, any one or more of operations830, 832, 930, and 932 may be performed, as appropriate, in accordancewith the above discussions of those operations.

In operation 1060, the touch input detector 610 detects (e.g., via,using, in conjunction with, or otherwise based on the display screen101) a touch input (e.g., a single tap or a double tap) at a location ofthe display screen 101 where the GUI 110 is presenting (e.g.,displaying) the sequentially second alphabetic letter 122 (e.g., “A”)within the word 120. In response, in operation 1062, the phonemepresentation generator 620 presents the second phoneme that correspondsto the sequentially second alphabetic letter 122 of the word 120. Such apresentation may be performed in a manner similar to that describedabove for the second phoneme. For example, any one or more of operations840, 842, 940, and 942 may be performed, as appropriate, in accordancewith the above discussions of those operations.

In situations where the word 120 (e.g., “CAT”) has a sequentially thirdalphabetic letter (e.g., “T”), one or both of operations 1080 and 1082may be performed in a manner similar to that described above foroperations 720 and 740. In operation 1080, the touch input detector 610detects (e.g., via, using, in conjunction with, or otherwise based onthe display screen 101) that the touch-and-drag input that began withinthe first zone of the slider control 130 and entered the second zone ofthe slider control 130 has entered a third zone of the slider control130. As noted above, the third zone may correspond to the sequentiallythird alphabetic letter 123 (e.g., “T”) and may be visually aligned withthe sequentially third alphabetic letter 123. This may be the case whenthe word 120 is three letters long or longer, including when the word120 is a CVC word.

In operation 1082, the phoneme presentation generator 620 responds tothe touch-and-drag input entering the third zone of the slider control130 by presenting a third phoneme that corresponds to the sequentiallythird alphabetic letter 123 of the word 120. The presenting of the thirdphoneme may include performing or otherwise causing audio playback ofthe third phoneme (e.g., among other things). Specifically, such apresentation of the third phoneme may be performed in a manner similarto that described above for the second phoneme. For example, one or moreoperations analogous to any one or more of operations 840, 842, 940, and942 may be performed for the third phoneme, as appropriate, inaccordance with the above discussions of those operations.

Furthermore, in situations where the word 120 (e.g., “BABY”) has asequentially fourth alphabetic letter (e.g., “Y”), one or moreoperations analogous to operations 1080 and 1082 may be performed. Forexample, the touch input detectors 610 may detect that thetouch-and-drag input that began within the first zone of the slidercontrol 130, entered the second zone of the slider control 130, andentered the third zone of the slider control 130 has now entered afourth zone of the slider control 130. The fourth zone may correspond tothe sequentially fourth alphabetic letter 123 (e.g., “Y”) and may bevisually aligned with the sequentially fourth alphabetic letter.

Likewise, the phoneme presentation generator 620 may respond to thetouch-and-drag input entering the fourth zone of the slider control 130by presenting a fourth phoneme that corresponds to the sequentiallyfourth alphabetic letter (e.g., “Y”) of the word 120. The presenting ofthe fourth phoneme may include performing or otherwise causing audioplayback of the fourth phoneme (e.g., among other things). Such apresentation of the fourth phoneme may be performed in a manner similarto that described above for the second or third phoneme. For example,one or more operations analogous to any one or more of operations 840,842, 940, and 942 may be performed for the fourth phoneme, asappropriate, in accordance with the above discussions of thoseoperations.

According to various example embodiments, when the word 120 has five ormore alphabetic letters, the additional alphabetic letters beyond thesequentially fourth alphabetic letter may be handled by the machine 100in a manner similar to that described above for the sequentially fourthalphabetic letter.

According to various example embodiments, one or more of themethodologies described herein may facilitate variable-speedpronunciation of phonemes by the machine 100. Moreover, one or more ofthe methodologies described herein may facilitate technical improvementsover other machines that pronounce phonemes or attempt to pronouncephonemes, including being more responsive to a user (e.g., as the userdynamically varies the speed of the touch-and-drag input), providing agreater degree of control (e.g., over the speed at which the word ispronounced) to the user, providing more natural sounding auditoryfeedback to the user (e.g., at high pronunciation speeds, at lowpronunciation speeds, or both), providing more natural looking visualfeedback (e.g., in the form of animated mouth movements presented on adisplay screen) to the user, enabling the user to quickly andconveniently experiment with several different pronunciation speeds fora word (e.g., by repeatedly pronouncing the word in response to repeatedtouch-and-drag inputs at different speeds), or any suitable combinationthereof. Hence, one or more of the methodologies described herein mayfacilitate teaching or learning of reading skills, as well as enhanceuser enjoyment thereof, compared to capabilities of pre-existing systemsand methods.

When these effects are considered in aggregate, one or more of themethodologies described herein may obviate a need for certain efforts orresources that otherwise would be involved in variable-speedpronunciation of phonemes or other tasks involved in teaching orlearning of reading skills. Efforts expended by a user in performingthese tasks may be reduced by use of (e.g., reliance upon) aspecial-purpose machine that implements one or more of the methodologiesdescribed herein. Computing resources used by one or more systems ormachines (e.g., within a network environment) may similarly be reduced(e.g., compared to systems or machines that lack the structuresdiscussed herein or are otherwise unable to perform the functionsdiscussed herein). Examples of such computing resources includeprocessor cycles, network traffic, computational capacity, main memoryusage, graphics rendering capacity, graphics memory usage, data storagecapacity, power consumption, and cooling capacity.

FIG. 11 is a block diagram illustrating components of a machine 1100,according to some example embodiments, able to read instructions 1124from a machine-readable medium 1122 (e.g., a non-transitorymachine-readable medium, a machine-readable storage medium, acomputer-readable storage medium, or any suitable combination thereof)and perform any one or more of the methodologies discussed herein, inwhole or in part. Specifically, FIG. 11 shows the machine 1100 in theexample form of a computer system (e.g., a computer) within which theinstructions 1124 (e.g., software, a program, an application, an applet,an app, or other executable code) for causing the machine 1100 toperform any one or more of the methodologies discussed herein may beexecuted, in whole or in part.

In alternative embodiments, the machine 1100 operates as a standalonedevice or may be communicatively coupled (e.g., networked) to othermachines. In a networked deployment, the machine 1100 may operate in thecapacity of a server machine or a client machine in a server-clientnetwork environment, or as a peer machine in a distributed (e.g.,peer-to-peer) network environment. The machine 1100 may be a servercomputer, a client computer, a personal computer (PC), a tabletcomputer, a laptop computer, a netbook, a cellular telephone, a smartphone, a set-top box (STB), a personal digital assistant (PDA), a webappliance, a network router, a network switch, a network bridge, or anymachine capable of executing the instructions 1124, sequentially orotherwise, that specify actions to be taken by that machine. Further,while only a single machine is illustrated, the term “machine” shallalso be taken to include any collection of machines that individually orjointly execute the instructions 1124 to perform all or part of any oneor more of the methodologies discussed herein.

The machine 1100 includes a processor 1102 (e.g., one or more centralprocessing units (CPUs), one or more graphics processing units (GPUs),one or more digital signal processors (DSPs), one or more applicationspecific integrated circuits (ASICs), one or more radio-frequencyintegrated circuits (RFICs), or any suitable combination thereof), amain memory 1104, and a static memory 1106, which are configured tocommunicate with each other via a bus 1108. The processor 1102 containssolid-state digital microcircuits (e.g., electronic, optical, or both)that are configurable, temporarily or permanently, by some or all of theinstructions 1124 such that the processor 1102 is configurable toperform any one or more of the methodologies described herein, in wholeor in part. For example, a set of one or more microcircuits of theprocessor 1102 may be configurable to execute one or more modules (e.g.,software modules) described herein. In some example embodiments, theprocessor 1102 is a multicore CPU (e.g., a dual-core CPU, a quad-coreCPU, an 8-core CPU, or a 128-core CPU) within which each of multiplecores behaves as a separate processor that is able to perform any one ormore of the methodologies discussed herein, in whole or in part.Although the beneficial effects described herein may be provided by themachine 1100 with at least the processor 1102, these same beneficialeffects may be provided by a different kind of machine that contains noprocessors (e.g., a purely mechanical system, a purely hydraulic system,or a hybrid mechanical-hydraulic system), if such a processor-lessmachine is configured to perform one or more of the methodologiesdescribed herein.

The machine 1100 may further include a graphics display 1110 (e.g., aplasma display panel (PDP), a light emitting diode (LED) display, aliquid crystal display (LCD), a projector, a cathode ray tube (CRT), orany other display capable of displaying graphics or video). The machine1100 may also include an alphanumeric input device 1112 (e.g., akeyboard or keypad), a pointer input device 1114 (e.g., a mouse, atouchpad, a touchscreen, a trackball, a joystick, a stylus, a motionsensor, an eye tracking device, a data glove, or other pointinginstrument), a data storage 1116, an audio generation device 1118 (e.g.,a sound card, an amplifier, a speaker, a headphone jack, or any suitablecombination thereof), and a network interface device 1120.

The data storage 1116 (e,g., a data storage device) includes themachine-readable medium 1122 (e.g., a tangible and non-transitorymachine-readable storage medium) on which are stored the instructions1124 embodying any one or more of the methodologies or functionsdescribed herein. The instructions 1124 may also reside, completely orat least partially, within the main memory 1104, within the staticmemory 1106, within the processor 1102 (e.g., within the processor'scache memory), or any suitable combination thereof, before or duringexecution thereof by the machine 1100. Accordingly, the main memory1104, the static memory 1106, and the processor 1102 may be consideredmachine-readable media (e,g., tangible and non-transitorymachine-readable media). The instructions 1124 may be transmitted orreceived over the network 190 via the network interface device 1120. Forexample, the network interface device 1120 may communicate theinstructions 1124 using any one or more transfer protocols (e.g.,hypertext transfer protocol (HTTP)).

In some example embodiments, the machine 1100 may be a portablecomputing device (e.g., a smart phone, a tablet computer, or a wearabledevice) and may have one or more additional input components 1130 (e.g.,sensors or gauges). Examples of such input components 1130 include animage input component (e.g., one or more cameras), an audio inputcomponent (e.g., one or more microphones), a direction input component(e.g., a compass), a location input component (e.g., a globalpositioning system (GPS) receiver), an orientation component (e.g., agyroscope), a motion detection component (e.g., one or moreaccelerometers), an altitude detection component (e.g., an altimeter), atemperature input component (e.g., a thermometer), and a gas detectioncomponent (e.g., a gas sensor). Input data gathered by any one or moreof these input components 1130 may be accessible and available for useby any of the modules described herein (e.g., with suitable privacynotifications and protections, such as opt-in consent or opt-outconsent, implemented in accordance with user preference, applicableregulations, or any suitable combination thereof).

As used herein, the term “memory” refers to a machine-readable mediumable to store data temporarily or permanently and may be taken toinclude, but not be limited to, random-access memory (RAM), read-onlymemory (ROM), buffer memory, flash memory, and cache memory. While themachine-readable medium 1122 is shown in an example embodiment to be asingle medium, the term “machine-readable medium” should be taken toinclude a single medium or multiple media (e.g., a centralized ordistributed database, or associated caches and servers) able to storeinstructions. The term “machine-readable medium” shall also be taken toinclude any medium, or combination of multiple media, that is capable ofcarrying (e.g., storing or communicating) the instructions 1124 forexecution by the machine 1100, such that the instructions 1124, whenexecuted by one or more processors of the machine 1100 (e.g., processor1102), cause the machine 1100 to perform any one or more of themethodologies described herein, in whole or in part. Accordingly, a“machine-readable medium” refers to a single storage apparatus ordevice, as well as cloud-based storage systems or storage networks thatinclude multiple storage apparatus or devices. The term“machine-readable medium” shall accordingly be taken to include, but notbe limited to, one or more tangible and non-transitory data repositories(e.g., data volumes) in the example form of a solid-state memory chip,an optical disc, a magnetic disc, or any suitable combination thereof.

A “non-transitory” machine-readable medium, as used herein, specificallyexcludes propagating signals per se. According to various exampleembodiments, the instructions 1124 for execution by the machine 1100 canbe communicated via a carrier medium (e.g., a machine-readable carriermedium). Examples of such a carrier medium include a non-transientcarrier medium (e.g., a non-transitory machine-readable storage medium,such as a solid-state memory that is physically movable from one placeto another place) and a transient carrier medium (e.g., a carrier waveor other propagating signal that communicates the instructions 1124).

Certain example embodiments are described herein as including modules.Modules may constitute software modules (e.g., code stored or otherwiseembodied in a machine-readable medium or in a transmission medium),hardware modules, or any suitable combination thereof. A “hardwaremodule” is a tangible (e.g., non-transitory) physical component (e.g., aset of one or more processors) capable of performing certain operationsand may be configured or arranged in a certain physical manner. Invarious example embodiments, one or more computer systems or one or morehardware modules thereof may be configured by software (e.g., anapplication or portion thereof) as a hardware module that operates toperform operations described herein for that module.

In some example embodiments, a hardware module may be implementedmechanically, electronically, hydraulically, or any suitable combinationthereof. For example, a hardware module may include dedicated circuitryor logic that is permanently configured to perform certain operations. Ahardware module may be or include a special-purpose processor, such as afield programmable gate array (FPGA) or an ASIC. A hardware module mayalso include programmable logic or circuitry that is temporarilyconfigured by software to perform certain operations. As an example, ahardware module may include software encompassed within a CPU or otherprogrammable processor. It will be appreciated that the decision toimplement a hardware module mechanically, hydraulically, in dedicatedand permanently configured circuitry, or in temporarily configuredcircuitry (e.g., configured by software) may be driven by cost and timeconsiderations.

Accordingly, the phrase “hardware module” should be understood toencompass a tangible entity that may be physically constructed,permanently configured (e.g., hardwired), or temporarily configured(e.g., programmed) to operate in a certain manner or to perform certainoperations described herein. Furthermore, as used herein, the phrase“hardware-implemented module” refers to a hardware module. Consideringexample embodiments in which hardware modules are temporarily configured(e.g., programmed), each of the hardware modules need not be configuredor instantiated at any one instance in time. For example, where ahardware module includes a CPU configured by software to become aspecial-purpose processor, the CPU may be configured as respectivelydifferent special-purpose processors (e.g., each included in a differenthardware module) at different times. Software (e.g., a software module)may accordingly configure one or more processors, for example, to becomeor otherwise constitute a particular hardware module at one instance oftime and to become or otherwise constitute a different hardware moduleat a different instance of time.

Hardware modules can provide information to, and receive informationfrom, other hardware modules. Accordingly, the described hardwaremodules may be regarded as being communicatively coupled. Where multiplehardware modules exist contemporaneously, communications may be achievedthrough signal transmission (e.g., over circuits and buses) between oramong two or more of the hardware modules. In embodiments in whichmultiple hardware modules are configured or instantiated at differenttimes, communications between such hardware modules may be achieved, forexample, through the storage and retrieval of information in memorystructures to which the multiple hardware modules have access. Forexample, one hardware module may perform an operation and store theoutput of that operation in a memory (e.g., a memory device) to which itis communicatively coupled. A further hardware module may then, at alater time, access the memory to retrieve and process the stored output.Hardware modules may also initiate communications with input or outputdevices, and can operate on a resource (e.g., a collection ofinformation from a computing resource).

The various operations of example methods described herein may beperformed, at least partially, by one or more processors that aretemporarily configured (e.g., by software) or permanently configured toperform the relevant operations. Whether temporarily or permanentlyconfigured, such processors may constitute processor-implemented modulesthat operate to perform one or more operations or functions describedherein. As used herein, “processor-implemented module” refers to ahardware module in which the hardware includes one or more processors.Accordingly, the operations described herein may be at least partiallyprocessor-implemented, hardware-implemented, or both, since a processoris an example of hardware, and at least some operations within any oneor more of the methods discussed herein may be performed by one or moreprocessor-implemented modules, hardware-implemented modules, or anysuitable combination thereof.

Moreover, such one or more processors may perform operations in a “cloudcomputing” environment or as a service (e.g., within a “software as aservice” (SaaS) implementation). For example, at least some operationswithin any one or more of the methods discussed herein may be performedby a group of computers (e.g., as examples of machines that includeprocessors), with these operations being accessible via a network (e.g.,the Internet) and via one or more appropriate interfaces (e.g., anapplication program interface (API)). The performance of certainoperations may be distributed among the one or more processors, whetherresiding only within a single machine or deployed across a number ofmachines. In some example embodiments, the one or more processors orhardware modules (e.g., processor-implemented modules) may be located ina single geographic location (e.g., within a home environment, an officeenvironment, or a server farm). In other example embodiments, the one ormore processors or hardware modules may be distributed across a numberof geographic locations.

Throughout this specification, plural instances may implementcomponents, operations, or structures described as a single instance.Although individual operations of one or more methods are illustratedand described as separate operations, one or more of the individualoperations may be performed concurrently, and nothing requires that theoperations be performed in the order illustrated. Structures and theirfunctionality presented as separate components and functions in exampleconfigurations may be implemented as a combined structure or componentwith combined functions. Similarly, structures and functionalitypresented as a single component may be implemented as separatecomponents and functions. These and other variations, modifications,additions, and improvements fall within the scope of the subject matterherein.

Some portions of the subject matter discussed herein may be presented interms of algorithms or symbolic representations of operations on datastored as bits or binary digital signals within a memory (e.g., acomputer memory or other machine memory). Such algorithms or symbolicrepresentations are examples of techniques used by those of ordinaryskill in the data processing arts to convey the substance of their workto others skilled in the art. As used herein, an “algorithm” is aself-consistent sequence of operations or similar processing leading toa desired result. In this context, algorithms and operations involvephysical manipulation of physical quantities. Typically, but notnecessarily, such quantities may take the form of electrical, magnetic,or optical signals capable of being stored, accessed, transferred,combined, compared, or otherwise manipulated by a machine. It isconvenient at times, principally for reasons of common usage, to referto such signals using words such as “data,” “content,” “bits,” “values,”“elements,” “symbols,” “characters,” “terms,” “numbers,” “numerals,” orthe like. These words, however, are merely convenient labels and are tobe associated with appropriate physical quantities.

Unless specifically stated otherwise, discussions herein using wordssuch as “accessing,” “processing,” “detecting,” “computing,”“calculating,” “determining,” “generating,” “presenting,” “displaying,”or the like refer to actions or processes performable by a machine(e.g., a computer) that manipulates or transforms data represented asphysical (e.g., electronic, magnetic, or optical) quantities within oneor more memories (e.g., volatile memory, non-volatile memory, or anysuitable combination thereof), registers, or other machine componentsthat receive, store, transmit, or display information. Furthermore,unless specifically stated otherwise, the terms “a” or “an” are hereinused, as is common in patent documents, to include one or more than oneinstance. Finally, as used herein, the conjunction “or” refers to anon-exclusive “or,” unless specifically stated otherwise.

The following enumerated descriptions describe various examples ofmethods, machine-readable media, and systems (e.g., machines, devices,or other apparatus) discussed herein.

A first example provides a method comprising:

-   presenting, by one or more processors of a machine, a graphical user    interface (GUI) on a touch-sensitive display screen of a device, the    GUI depicting a slider control aligned with a word that includes a    sequentially first alphabetic letter and a sequentially second    alphabetic letter, a first zone of the slider control corresponding    to the sequentially first alphabetic letter of the word, a second    zone of the slider control corresponding to the sequentially second    alphabetic letter of the word;-   detecting, via the touch-sensitive display screen and by one or more    processors of the machine, a touch-and-drag input that begins within    the first zone of the slider control and enters the second zone of    the slider control;-   by one or more processors of the machine and in response to the    touch-and-drag input beginning within the first zone of the slider    control, presenting a first phoneme that corresponds to the    sequentially first alphabetic letter of the word, the presenting of    the first phoneme including audio playback of the first phoneme; and-   by one or more processors of the machine and in response to the    touch-and-drag input entering the second zone of the slider control,    presenting a second phoneme that corresponds to the sequentially    second alphabetic letter of the word, the presenting of the second    phoneme including audio playback of the second phoneme.

A second example provides a method according to the first example,wherein:

-   the sequentially first alphabetic letter is a vowel, and the first    phoneme is a vowel phoneme; and-   the presenting of the first phoneme includes sustaining the audio    playback of the vowel phoneme by repeatedly looping at least a    portion of the vowel phoneme as long as the touch-and-drag input    remains within the first zone of the slider control. Thus, where the    first letter of the word is a vowel, the presenting of the    corresponding vowel phoneme is prolonged (e.g., performed for a    prolonged duration) by the repeated looping of at least the portion    of the vowel phoneme.

A third example provides a method according to the first example or thesecond example, wherein:

-   the sequentially second alphabetic letter is a vowel, and the second    phoneme is a vowel phoneme; and-   the presenting of the second phoneme includes sustaining the audio    playback of the vowel phoneme by repeatedly looping at least a    portion of the vowel phoneme as long as the touch-and-drag input    remains within the second zone of the slider control. Thus, where    the second letter of the word is a vowel, the presenting of the    corresponding vowel phoneme is prolonged (e.g., performed for a    prolonged duration) by the repeated looping of at least the portion    of the vowel phoneme.

A fourth example provides a method according to the first example,wherein:

-   the sequentially first alphabetic letter is a consonant, and the    first phoneme is a consonant phoneme; and-   the presenting of the first phoneme includes, after the audio    playback of the consonant phoneme, audio playback of silence as long    as the touch-and-drag input remains within the first zone of the    slider control. Thus, where the first letter of the word is a    consonant, the presenting of the corresponding consonant phoneme is    not prolonged but instead performed for a fixed duration by the    repeated playback (e.g., by looping) of silence after the playback    of the consonant phoneme.

A fifth example provides a method according to the first example or thefourth example, wherein:

-   the sequentially second alphabetic letter is a consonant, and the    second phoneme is a consonant phoneme; and-   the presenting of the second phoneme includes, after the audio    playback of the consonant phoneme, audio playback of silence as long    as the touch-and-drag input remains within the second zone of the    slider control. Thus, where the second letter of the word is a    consonant, the presenting of the corresponding consonant phoneme is    not prolonged but instead performed for a fixed duration by the    repeated playback (e.g., by looping) of silence after the playback    of the consonant phoneme.

A sixth example provides a method according to any of the first throughfifth examples, wherein:

-   the detected touch-and-drag input has a duration and triggers a    presenting of a pronunciation of the word coextensive with the    duration of the touch-and-drag input; and-   the presenting of the pronunciation of the word includes the    presenting of the first and second phonemes within the duration of    the touch-and-drag input. Thus, where the touch-and-drag input is a    swipe gesture, the duration of the swipe gesture determines the    duration of the pronunciation of the full word in its entirety.

A seventh example provides a method according to any of the firstthrough sixth examples, wherein:

-   the detected touch-and-drag input has a movement speed and triggers    a presenting of a pronunciation of the word at a speech speed    determined based on the movement speed of the touch-and-drag input;    and-   the presenting of the pronunciation of the word includes the    presenting of the first and second phonemes at the speech speed    determined based on the movement speed of the touch-and-drag input.    Thus, where the touch-and-drag input is a swipe gesture, the speed    (e.g., velocity) of the swipe gesture determines the speed of the    pronunciation of the full word in its entirety.

An eighth example provides a method according to any of the firstthrough seventh examples, wherein:

-   the GUI further depicts an animated mouth;-   the presenting of the first phoneme further includes displaying the    animated mouth in a first mouth shape that corresponds to the first    phoneme during the audio playback of the first phoneme; and-   the presenting of the second phoneme further includes displaying the    animated mouth in a second mouth shape that corresponds to the    second phoneme during the audio playback of the second phoneme.    Thus, where an animated avatar or other animated character is    depicted in the GUI, its animated mouth may change shape in    accordance (e.g., in unison) with the audio playback of each    sequential phoneme.

A ninth example provides a method according to any of the first througheighth examples, wherein:

Accordingly,    by extension, as each sequential letter of the word is pronounced,    that letter may be highlighted by a corresponding change in color.

A tenth example provides a method according to any of the first throughninth examples, further comprising:

-   detecting, via the touch-sensitive display screen, a touch input on    the sequentially first alphabetic letter of the word; and-   in response to the touch input, presenting the first phoneme that    corresponds to the sequentially first alphabetic letter of the word,    the presenting of the first phoneme including audio playback of the    first phoneme. Accordingly, a user (e.g., a child who is learning to    read) can touch each letter of the word (e.g., the first letter) one    by one to hear its corresponding phoneme.

An eleventh example provides a method according to any of the firstthrough tenth examples, further comprising:

-   detecting, via the touch-sensitive display screen, a touch input on    the sequentially second alphabetic letter of the word; and-   in response to the touch input, presenting the second phoneme that    corresponds to the sequentially second alphabetic letter of the    word, the presenting of the second phoneme including audio playback    of the second phoneme. Accordingly, a user (e.g., a child who is    learning to read) can touch each letter of the word (e.g., the    second letter) one by one to hear its corresponding phoneme.

A twelfth example provides a method according to any of the firstthrough eleventh examples, wherein:

-   the word is a consonant-vowel-consonant word (e.g., “cat” or “dog”)    in which the sequentially first alphabetic letter is a first    consonant, the sequentially second alphabetic letter is a vowel, and    a sequentially third alphabetic letter is a second consonant;-   the first phoneme is a first consonant phoneme, the second phoneme    is a vowel phoneme, and the sequentially third alphabetic letter    corresponds to a second consonant phoneme;-   the presenting of the first phoneme includes, after the audio    playback of the first consonant phoneme, audio playback of silence    as long as the touch-and-drag input remains within the first zone of    the slider control;-   the presenting of the second phoneme includes sustaining the audio    playback of the vowel phoneme by repeatedly looping at least a    portion of the vowel phoneme as long as the touch-and-drag input    remains within the second zone of the slider control; and-   the method further comprises:-   detecting, via the touch-sensitive display screen, that the    touch-and-drag input entered a third zone of the slider control, the    third zone corresponding to the sequentially third alphabetic letter    of the word; and-   in response to the touch-and-drag input entering the third zone of    the slider control, presenting the second consonant phoneme that    corresponds to the sequentially third alphabetic letter of the word,    the presenting of the second consonant phoneme including audio    playback of the second consonant phoneme followed by audio playback    of silence as long as the touch-and-drag input remains within the    third zone of the slider control. Accordingly, by extension, words    longer than three letters may be pronounced in a similar manner    (e.g., letter by letter, phoneme by phoneme, or both).

A thirteenth example provides a machine-readable medium (e.g., anon-transitory machine-readable storage medium) comprising instructionsthat, when executed by one or more processors of a machine, cause themachine to perform operations comprising:

Thus, where the first letter of the word is a vowel,    the presenting of the corresponding vowel phoneme is prolonged    (e.g., performed for a prolonged duration) by the repeated looping    of at least the portion of the vowel phoneme.

A fifteenth example provides a machine-readable medium according to thethirteenth example or the fourteenth example, wherein:

-   the sequentially second alphabetic letter is a vowel, and the second    phoneme is a vowel phoneme; and-   the presenting of the second phoneme includes sustaining the audio    playback of the vowel phoneme by repeatedly looping at least a    portion of the vowel phoneme as long as the touch-and-drag input    remains within the second zone of the slider control. Thus, where    the second letter of the word is a vowel, the presenting of the    corresponding vowel phoneme is prolonged (e.g., performed for a    prolonged duration) by the repeated looping of at least the portion    of the vowel phoneme.

A sixteenth example provides a machine-readable medium according to anyof the thirteenth through fifteenth examples, wherein:

-   the GUI further depicts an animated mouth;-   the presenting of the first phoneme further includes displaying the    animated mouth in a first mouth shape that corresponds to the first    phoneme during the audio playback of the first phoneme; and-   the presenting of the second phoneme further includes displaying the    animated mouth in a second mouth shape that corresponds to the    second phoneme during the audio playback of the second phoneme.    Thus, where an animated avatar or other animated character is    depicted in the GUI, its animated mouth may change shape in    accordance (e.g., in unison) with the audio playback of each    sequential phoneme.

A seventeenth example provides a system (e.g., a computer system orother data processing machine) comprising:

An eighteenth example provides a system according to the seventeenthexample, wherein:

-   the sequentially second alphabetic letter is a vowel, and the second    phoneme is a vowel phoneme; and-   the presenting of the second phoneme includes sustaining the audio    playback of the vowel phoneme by repeatedly looping at least a    portion of the vowel phoneme as long as the touch-and-drag input    remains within the second zone of the slider control. Thus, where    the second letter of the word is a vowel, the presenting of the    corresponding vowel phoneme is prolonged (e.g., performed for a    prolonged duration) by the repeated looping of at least the portion    of the vowel phoneme.

A nineteenth example provides a system according to the seventeenthexample or the eighteenth example, wherein:

-   the detected touch-and-drag input has a duration and triggers a    presenting of a pronunciation of the word coextensive with the    duration of the touch-and-drag input; and-   the presenting of the pronunciation of the word includes the    presenting of the first and second phonemes within the duration of    the touch-and-drag input. Thus, where the touch-and-drag input is a    swipe gesture, the duration of the swipe gesture determines the    duration of the pronunciation of the full word in its entirety.

A twentieth example provides a system according to any of theseventeenth through nineteenth examples, wherein:

-   the GUI further depicts an animated mouth;-   the presenting of the first phoneme further includes displaying the    animated mouth in a first mouth shape that corresponds to the first    phoneme during the audio playback of the first phoneme; and-   the presenting of the second phoneme further includes displaying the    animated mouth in a second mouth shape that corresponds to the    second phoneme during the audio playback of the second phoneme.
